Question

我正在编写一个bash脚本来格式化.csv文件的输出，在这里我使用pssh在1000台以上的服务器上运行命令（保存在/ tmp / hosts中），我能够通过一行来管理命令输出插入逗号“，”但不能将所有内容都放在一行注意：服务器名称下面仅是一个示例，实际上，服务器名称是不同的，并且OS命令基于用户的输入。

我尝试在命令之间使用-'echo“ $（uname -a），$（date）”'在命令之间添加“，”。但是无法保持一致，就像我在下面期望的那样。

我正在使用以下命令

pssh -h /tmp/hosts -x '-q -o StrictHostKeyChecking=no -o GSSAPIAuthentication=no -o PreferredAuthentications=publickey -o PubkeyAuthentication=yes' -i 'echo "$(uname -a), $(date)"'

Answer 1

换行符由pssh实用程序插入。您可以尝试在--inline实用程序中使用选项--inline-stdout或pssh。或使用-o选项设置输出目录，然后使用bash脚本根据您的需要正确格式化输出。

Answer 2

grep pattern file | awk '{print}' ORS='" '

将操作系统命令输出保持在一行
